Partially embedding of the quantum mechanical analog of the nonlinear sigma model
R. Amorim, J. Barcelos-Neto, C. Wotzasek
We consider the quantum mechanical analog of the nonlinear sigma model. There are difficulties to completely embed this theory by directly using the Batalin, Fradkin, Fradkina, and…

Extended supersymmetry in D=1+1
R. Amorim, J. Barcelos-Neto
We extend superspace by introducing an antisymmetric tensorial coordinate. The resulting theory presents a supersymmetry with central charge. After integrating over the tensorial c…
